Pain After Dental Treatment: Fillings, Root Canals, Crowns
This page is general information and does not replace an examination.
Some pain after dental treatment, usually soreness or sensitivity, is common. Fillings, cleanings and other treatments can cause short-term sensitivity[1], and after root canal treatment the area may feel swollen and sore for a while[2]. In a systematic review of 72 studies, pain was reported by about 40% of patients 24 hours after root canal treatment and by 11% after one week[3]. Pain that gets worse instead of better, sharp pain every time you bite, swelling or a high temperature are reasons to contact your dentist[5].

What is normal after dental treatment
Pain after dental treatment is usually a sign that the tooth and the tissues around it are reacting to the work done, and it normally fades day by day. After the local anaesthetic, your jaw and face may stay numb for several hours[2]. After that, a treated tooth can be sensitive to cold or sweet things for a short time: fillings, cleanings and other treatments can all cause short-term sensitivity[1].
What matters is the direction. Discomfort that is a little less each day is the usual pattern. Pain that grows, wakes you at night, comes every time you bite, or comes with swelling or a high temperature needs a dentist[5]. This page explains the usual course after fillings, root canal treatment and crowns, and links to our separate aftercare guides for extractions and implants.
Pain after a filling
Sensitivity to cold or sweet. Short-term sensitivity after a filling is common and often settles on its own[1]. A systematic review of randomised trials on back-tooth composite fillings found that the type of bonding system used did not change the risk or intensity of this sensitivity[6], so it is a reaction of the tooth rather than a sign that the wrong material was used.
Pain when you bite. If a newly filled tooth hurts when you bite or chew, the filling may be slightly too high and needs to be checked; pain when biting is one of the signs the NHS lists for seeing a dentist[5]. Adjusting the bite is quick, and a filling that stays too high keeps the tooth sore.
Lingering or throbbing pain. A deep cavity close to the nerve can leave the nerve inflamed even after a good filling. Pain that lasts longer after a cold drink, throbs, or starts on its own, especially at night, should be checked; the dentist tests the tooth and takes an X-ray, and some teeth then need root canal treatment. A crack in the tooth can also cause pain on biting and to cold[10].
Filling types, how long they last and what to do when a filling falls out are covered in dental fillings. If several teeth are sensitive, not only the filled one, read sensitive teeth.
Pain after root canal treatment
Root canal treatment removes the inflamed or infected pulp and seals the tooth; afterwards the area around the tooth may feel swollen and sore, and it should get better in a couple of weeks[2]. The numbers are reassuring. A systematic review of 72 studies found that pain was present in about 81% of patients before treatment, 40% at 24 hours after treatment and 11% after one week. Average pain severity on a 100-point scale fell from 54 before treatment to 24 at 24 hours and 5 at one week[3].
One visit or two? A 2022 Cochrane review (47 trials) found no clear difference in failure seen on X-rays after at least a year (moderate-certainty evidence) between finishing root canal treatment in one visit or over several visits. Slightly more people reported some pain within the first week after single-visit treatment (moderate-certainty evidence), while pain up to 72 hours after the root filling did not differ clearly[4]. At our clinic root canal treatment is normally done in two sessions about 7 days apart; a tooth with a living nerve and no infection at the root tip, for example one treated before a crown, is often done in one session.
Between visits. You usually have a temporary filling between appointments[2]. If it falls out or the tooth swells, contact the clinic. Go to every follow-up appointment, take care not to knock the tooth, and keep up your cleaning[2]. A tooth that was badly broken down may need a crown afterwards[2].
The treatment itself is described on root canal treatment.
Pain after a crown, bridge or onlay
Preparing a tooth for a crown or onlay is treatment like any other, and short-term sensitivity afterwards is common[1]. Three situations are worth knowing:
- With the temporary crown. The prepared tooth can be sensitive to cold until the final crown is fitted. A temporary that comes loose should be re-fitted, because the tooth underneath is unprotected.
- A high bite. If the new crown hits first when you close, the tooth becomes sore on biting[5]. A small adjustment usually solves it.
- Pain that does not settle. Lingering pain to hot or cold, or pain on its own, means the nerve inside the tooth needs to be tested. A crack that was already in the tooth can also keep causing pain under a filling or crown[10].
Crowns and onlays are compared in inlay, onlay or crown; the materials we use are described in zirconia crowns.
After a cleaning, extraction, implant or whitening
- Deep cleaning: short-term sensitivity is common after cleanings[1]. See professional teeth cleaning.
- Tooth extraction: what to expect day by day, and the warning signs, are in tooth extraction aftercare. Severe pain that starts 2–3 days after an extraction is explained in dry socket.
- Dental implant: see dental implant aftercare.
- Whitening: whitening products can increase sensitivity[1]; how we manage it is on teeth whitening.
What helps at home
Pain relief as directed
Over-the-counter painkillers such as paracetamol or ibuprofen can help; a pharmacist can advise you[2][5]. Take them as directed on the package, unless your doctor or pharmacist has told you otherwise. An American Dental Association guideline found that anti-inflammatory painkillers (NSAIDs), alone or combined with paracetamol (acetaminophen), likely give better pain relief with a more favourable safety profile than opioids, and recommends non-opioid medicines first[7].Go easy on the tooth
Eat soft foods and avoid chewing with the sore tooth; avoid foods that are sweet, very hot or very cold[5].Keep cleaning
Brush gently with a soft toothbrush[5]. Keeping the area clean helps the gums settle.Do not place tablets on the gum
Painkillers work by being swallowed. Never put aspirin or any tablet next to the tooth.Do not smoke
Smoking can make some dental problems worse[5].
What we prescribe. When we prescribe a painkiller, it is usually an anti-inflammatory: most often diclofenac potassium, naproxen sodium when stronger pain is expected, and sometimes dexketoprofen. The choice and schedule are decided for each patient after reviewing your medical history; tell us about stomach problems, kidney disease, asthma, pregnancy, other painkillers you take and any blood thinner.
Antibiotics do not treat toothache. An American Dental Association guideline recommends against antibiotics for most dental pain from the nerve or root tip, and advises them only when there are signs of spreading infection, such as fever or malaise, or a high risk of it; treating the tooth itself comes first[8]. A 2024 Cochrane review likewise notes that guidelines reserve antibiotics for spreading infection or systemic involvement[9]. If you are given antibiotics, it is only after an examination.
How long does pain after dental treatment last?
| Treatment | What is usual | Contact your dentist if |
|---|---|---|
| Filling | Short-term sensitivity to cold or sweet that often settles on its own[1] | It hurts when you bite, gets worse, throbs or starts on its own[5] |
| Root canal treatment | Soreness in about 40% at 24 hours and 11% at one week; usually mild by then[3] | Pain increases, swelling appears, or the temporary filling is lost[2][5] |
| Crown, bridge or onlay | Short-term sensitivity after preparation[1] | The bite feels high, or pain to hot or cold lingers[5] |
| Cleaning | Short-term sensitivity[1] | Pain or bleeding does not settle |
| Extraction or implant | See the separate aftercare guides | As listed in those guides |
Swelling that spreads to the eye or neck, difficulty breathing or swallowing, a high temperature, or bleeding that will not stop is an emergency (see the box at the top of this page).
Emergency: facial swelling that spreads to the eye or neck, difficulty breathing or swallowing, high fever, or bleeding that will not stop: call 112 in Türkiye.
Soon: toothache that lasts more than 2 days or does not go away with painkillers, or comes with a high temperature, pain when you bite, red gums, a bad taste or a swollen cheek or jaw[5].
Watch and mention it: mild sensitivity that is a little less each day.
If a tooth we treated hurts
Dr. Ali Cem Ulubey and Dr. Surur Ulubey treat their patients themselves, so the dentist who treated your tooth is the one who checks it. Write to us on WhatsApp with what you feel and, if you can, a photo. A photo helps us decide how soon you should be seen; it does not replace an examination. In the clinic we check the bite, the restoration and the nerve, and take a periapical X-ray when a single tooth needs a closer look.
Back home abroad? If you have pain or an infection and need treatment before you can reach us, emergency treatment by another dentist without our prior written OK does not void the guarantee. Send us that dentist’s report, the X-ray and photos within 7 days. The full conditions are in our written dental guarantee.
If a tooth needs further treatment, these are the fees on our dental treatment prices page:
| Treatment | Fee |
|---|---|
| Composite filling (front-tooth aesthetic composite) | €60 (€120) |
| Filling with MTA pulp protection | €90 |
| Root canal treatment: 1 / 2 / 3 roots | €120 / €150 / €180 |
| Zirconia crown (Amann Girrbach) | €185 per tooth |
| E.max crown | €250 per tooth |
| Ceramic inlay or onlay (E.max) | €250 |
The consultation and the panoramic X-ray taken at the examination have no separate fee. Prices are indicative; your final written quote follows the examination and X-rays and is valid for 30 days. Unless the treatment plan changes, the written price does not change.
Frequently asked questions
Is it normal for a tooth to hurt after a filling?
Short-term sensitivity to cold or sweet after a filling is common and often settles on its own. It should be a little less each day. If the tooth hurts when you bite, the filling may be slightly high and needs adjusting. Pain that lingers, throbs or starts on its own should be checked, because the nerve may be inflamed.
How long does pain last after root canal treatment?
In a systematic review of 72 studies, about 40% of patients had some pain 24 hours after root canal treatment and about 11% after one week, and the average severity was low by then. The NHS says the area may feel swollen and sore but should get better in a couple of weeks. Increasing pain or swelling needs a dentist.
Why does my tooth hurt when I bite after a filling or crown?
The most common reason is that the new filling or crown is slightly too high, so that tooth takes all the force when you close. The dentist checks the bite and adjusts it, which is usually quick. If biting pain continues afterwards, the tooth is checked for a crack or an inflamed nerve.
Do I need antibiotics for pain after dental treatment?
Usually not. Dental guidelines recommend against antibiotics for most toothache from the nerve or root tip, because they do not relieve that pain and can cause harm. They are used when there are signs of spreading infection, such as fever, malaise or swelling, and only after an examination. Pain is treated by treating the tooth.
Which painkiller works for pain after dental treatment?
No single painkiller suits everyone. An American Dental Association guideline found that anti-inflammatory painkillers, alone or combined with paracetamol, likely give better relief with a more favourable safety profile than opioids. Over-the-counter products should be taken as directed on the package; ask your pharmacist or doctor if you have a medical condition or take other medicines.
My treated tooth hurts and I am back home. What should I do?
Write to us on WhatsApp with a description and, if possible, a photo or X-ray. If you have pain or an infection and need treatment before you can reach us, emergency treatment by another dentist without our prior written OK does not void the guarantee; send us that dentist’s report, the X-ray and photos within 7 days. Swelling that spreads or a high fever needs urgent local care.
